Radioactive contamination

Bianca Gomez Mr. Lewis Honors Chemistry 17 November 2017 Radon-Engineer Introduction: Radon is a colorless/odorless gas that comes from the radioactive decay of Uranium. Radon is commonly found in soil and is usually exposed to human beings through ingestion and inhalation. Most of Radon exposure is seen in many homes that are located in places where the soil beneath it contains a high concentration of it. Radon has been seen more often through sicknesses of people who are exposed to it, for…

This man helped shape nuclear chemistry and he even created the planetary atom model. Rutherford is also famous for his experiment of gold foil. Rutherford 's experiments, in which he bombarded gold foil with particles (alpha particles) from a radioactive source, led to the understanding of the atom. “What he noted was that although most of the particles passed right through the gold foil, a very small percentage (approximately 1 in 8000) would "bounce back". What exactly did this imply?”(The…

Australia has many already existing methods of disposing of radioactive waste materials, each with their own list of pros and cons. However, there are also many theoretical methods of disposing such waste that have not been put into action, and if one of these were to be better than an already existing method when put into practice surely it should be given more attention. Therefore, this presentation shall cover each of these topics in order to identify which method of disposal, theoretical or…

One of the most dangerous parts of the power plant is the core from where the reactions occur. In the core, nuclear rods produce a vast amount of heat. Since the nuclear rods are very radioactive, they are highly dangerous to the human person. In the event that there is a nuclear meltdown, radiation is released into the atmosphere. The aftermath of a meltdown can be very destructive to the environment around it. The nuclear radiation that…

Radiation is formed by the instability of an atom either having too many or too few of and type of particles within an atom 's.These type of particles can be either having too many or too few electrons, neutrons or protons and you have a radioactive element.The element becomes unstable as each part holds another part on so having too few means that the link may be too weak to hold it together then having too many means there pushing others off the particles as there are too many attached to…

The Yucca Mountain Project Nuclear waste is a problem that plagues the United States due to dilemmas surrounding its handling. A scientific consensus shows that the best way to get rid of nuclear waste is through geological disposal, however, this method creates several barriers. Geological disposal includes storing nuclear waste in an underground repository site in hopes of it being contained without the need of surveillance for thousands of years. Due to the fact that nuclear waste contains…

from radioactive materials • In the form of liquid excreted from many research fields • In the form of solid ranging from glassware of hospitals and contaminated trash, radiopharmaceutical laboratories, reprocessing of spent fuel or waste from the nuclear power plants. Nuclear waste known as potential hazard to the human health, international and national guidelines standards radioactive waste with radiation protection…

Chapter Six: Completing the Table…with a Bang 1. What is the difference between a “dirty” bomb and a conventional nuclear bomb? (1 mark) The difference between a “dirty” bomb and a conventional nuclear bomb is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and…

emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through solid lead (6 inches) or concrete (6 feet). By analyzing the human eye, scientists were able to develop a highly accurate system for identifying the age of a corpse. This method calls of the use of radioactive carbon.…

“All the Ares missions use Hermes to get to and from Mars. It’s really big and cost a lot so NASA only built one.” Pg 2. Hermes is the large spaceship used for the trip to Mars in the Ares 3 mission. It carries the Ares 3 crew from Earth to Mars’ orbit. “Hermes is powered by ion engines. They throw Argon out the back of the ship really fast to get a tiny amount of acceleration. The thing is, it doesn't take much reactant mass, so a little Argon (and a nuclear reactor to power things) let us…
